AA Sharing is a Web3-inspired app that helps couples, friends, or families strengthen their relationships by recording daily gratitude and building shared dreams — turning fleeting emotional moments into lasting onchain memories.

Core Features:

Gratitude Ledger Users record daily appreciation for one another with optional stablecoin (e.g. USDC) micro-contributions (e.g. “You cooked dinner – $2”). Each entry is stored onchain, creating a permanent record of emotional growth.

Shared Wallet & Goals Couples or partners pool contributions into a joint wallet to work toward shared savings goals — like a Bali trip, anniversary gift, or shared dream. (Future roadmap includes staking unused funds to earn yield.)

Smart Contract Partnership Logic A mutual agreement ensures that if the relationship ends, funds in the shared wallet are automatically split 50/50 via Flow smart contracts — ensuring transparency and fairness.

Cross-Chain Compatibility via Avail Nexus Partners using different chains (Ethereum, Arbitrum, Polygon) can seamlessly contribute to the same wallet using Avail’s bridgeAndExecute() function, making AA Sharing truly interoperable.

Mainstream Accessibility via Privy Onboarding is effortless: users log in using email-based embedded wallets powered by Privy, ensuring that even non-crypto users can start sharing gratitude with no prior wallet setup.

Why it matters: Love is intangible, fleeting, and often forgotten. AA Sharing brings emotional currency into programmable finance — letting people turn emotional labor into shared value and onchain intimacy. Whether you're building a life with someone, saving for a dream, or simply saying "thank you" — now there's a decentralized place to grow love.
